Transformer tester inspection and accident handling methods
Transformer tester is one of the key power electronic equipment problems in the power management system, and its safety is directly related to the stable development and operation of a system. The transformer DC resistance tester should be far away from strong electric fields, strong magnetic fields, and high-frequency equipment. The smaller the power supply disturbance, the better, and the lighting cable should be used. If the power disturbance is still large, the instrument can be powered by the communication and purification power supply, and the capacity of the communication and purification power supply should be greater than 200VA.
When the transformer resistance tester is in operation, if the LCD display is disordered and there is no response when pressing all the buttons, perhaps the measured value is far from the actual value, please press the reset button, or turn off the power supply, and then re-operate. Therefore, in the process of practicing economic operation, it is necessary to study and analyze the overload operation of the transformer measuring instrument, and grasp the inspection and accident handling methods during operation. When the transformer resistance tester is in operation, if the LCD display is disordered and there is no response when pressing all the buttons, perhaps the measured value is far from the actual value, please press the reset button, or turn off the power supply, and then re-operate.
The transformer tester is one of the key equipment in the power system. It has a complicated variety and complex structure. With the rapid economic growth, some power grid systems are aging or covered up, especially the load rate of the distribution transformer measuring instrument is constantly increasing. Frequent overloading leads to an increase in faults and a large increase in capacity. Therefore, it is of great significance to the maintenance and incident handling of the transformer measuring instrument, and it is of great significance to ensure the stable operation of the power system.
The overload management capability of the transformer tester refers to the ability to allow the transformer tester to operate beyond its rated capacity in a certain period of time in our country in order to meet the needs of people in a certain economic operation process. The purpose of the overload operation is different. The overload of the transformer measuring instrument can be divided into the overload under normal use and the overload under the general accident.
